Completion of error handling

[elfring]

Would you like to add more error handling for return values from functions like the following?

• fprintf ⇒ sljit_verbose_reg
• pthread_mutex_lock ⇒ open_dev_zero

[zherczeg]

I don't really understand your request. Do you want more error codes?

[elfring]

I suggest to avoid ignorance of return values a bit more. Would you like to detect every error situation as early as possible?

[zherczeg]

I will never check the return value of printf, but mutex lock can be, although it would be a libc bug if that function fails.

• Should file output failures get also any more development attention in addition to data synchronisation difficulties?
• How do you think about to improve static source code analysis also for this software?
